mine is a silent thunder champion, with the open breech. I got the standard (Hi/Lo) belt loop mount which i think they call sporting now, where the breech face goes to the center of the belt. theres a higher one where the center of the ejection port is centered on the belt, and there's also a drooped and offset probably for dedicated IPSC. i chose this one because of versatility. it's supposed to comes standard with this but i got a the higher one in quick mount and did't like it. Ronnie sent me the standard mount for free (Internationally!) for others, there are quick mounts, which i got for my mag carriers, also paddles and stabilizers.
I had to modify the holster a little because it is for a standard USP40. ronnie garrett e-mailed me very detailed instructions with pictures when i asked how to modify it. i had to raise the sight channel for my tall suppressor sights, and open up the front a bit for the threaded barrel. I used a heat gun and pencil for the process, and it's perfect now.
about the cant, it's perfectly adjustable. you could turn it up side down
On level 1 competitions, i wear this on a ranger belt, + hat and boots. It looks so western IMO, my buddies LOL at me
ok, those aren't cowboy boots...
